AUGUST E. ROEVER. OF BROOKLYN, NEW YORK.

DISH-WASHING MACHINE.

Application filed August 23, 1916, Serial No. 116,423. Renewed October 1, 1921.

To all whom it may concern Be it known that I, AUGUST E. Ronvnn, a subject of the German Emperor, having applied for naturalization as a citizen of the United States and received my first papers, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Dish-Washing Machines, of which the following is a s ecification.

This invention re ates to dish washing machines, the object of the invention being to provide an improved'a-pparatus of the class described by means of which dishes will be quickly and thoroughly cleansed by the comhined action of air and water.

A further object of the invention is the provision of an improved apparatus of the class described having means for removing the scum from the greasy water.

In the drawings accompanying and forming part of this specification, Figure 1 is a cross sectional view of this improved dishwashing apparatus; Fig. 2 is a detail view of the scum removing device; and Fig. 3 is a top view of this improved apparatus.

Similar characters of reference indicate corresponding parts in the several figures of the drawings.

This improved dish-washing machine In the preferred form thereof comprises a receptacle 2 provided with a removable cover 3. One side of this receptacle is provided with a fan housing or chamber 4 in communication with which is a plurality of pipes 5 having perforations along those p01- tions 6 thereof which extend along the bottom of the receptacle. Carried by the receptacle along the top thereof and extending through the fan housing is a shaft 7 suitably supported by the receptacle. Inside the housing and carried by the shaft 7 is a fan 8 and outside of the housing is a spur gear 9 in mesh with an annular gear 10 encircling a foraminous or perforated drum ll. located within the receptacle in such a mannor that the perforated pipes hereinbefore referred to will be between this drum and the receptacle 2. By means of the gear on the shaft and the annular gear, the drum will be rotated. For the purpose of supporting the annular gear and thereby the drum for rotation, the receptacle 2 is provided with a series of inwardly extending projections 12 carrying rolls 13 located under the ring gear. J ournaled in the bot- Speciflcation of Letters Patent.

Patented Nov. 8, 1921.

Serial No. 504,731.

tom of the receptacle 2 and extending through the drum is a hollow vertical shaft 15 having a beveled gear 16 at its upper end in mesh with a similar gear 17 carried by the horizontal shaft whereby the vertical shaft is rotated. These two bevel gears are suitably supported by a bracket 19 located on the horizontal and vertical shafts. Carried by this vertical shaft is a scum removing device consisting preferably of a curved blade 25 located in such a position that it will sweep the top of the water, thereby to remove the greasy scum and assist in its passage out through the foraminous casing or cause the scum to be forced into the hollow vertical shaft from which it may pass or be forced out from the casing in any suitable way as by a pipe 30.

For driving the horizontal shaft a motor 35 is shown supported on a suitable bracket 36 secured to the receptacle.

From the foregoing it will be observed that when the dishes are placed in the drum, this drum will be rotated and at the same time air will be forced by the fan into the drum to thoroughly cleanse the dishes, While the scum will be removed by the sweeping blade, thus providing a very simple and inexpensive dish-washing machine.

It will be understood that the various details may be more or less modified without departing from the spirit or scope of this improvement. For instance, the drum may be perforated only at its bottom, or at its bottom and part way up its side and may be of wire mesh or any other suitable material. I

As shown. it will be observed that the foraminous drum rotates in one direction and that the scum sweeping instrumentality rotates in the opposite direction, and that the fan, the drum and the-scum sweeping instrumentality are all operated simultaneously from a small motor, which may be readily placed in operation by the user whenever it is desired to use the apparatus. so that it requires no effort other than to place the dishes in the apparatus and remove them in order to wash them.

I claim as my invention:

1. In a dish washing machine, the combination of a water carrying receptacle, a foraminous drum located therein, means for rotating said drum horizontally and comprising a shaft, a fan chamber at one side of saidreceptacle, a motor driven rotary fan at the bottom thereof.

2. In a dish washing machine, the combination of a Water carrying receptacle, a foraminous drum located therein, motor driving means for rotating said drum horizontally and comprising a motor carried by the receptacle exteriorly thereof, and a horizontal shaft connected with said motor, a fan chamber at one side of the receptacle and at the inner side of the motor and into which said shaft extends, a rotary fan in said chamber and connected with said shaft, and a conduit connecting said chamber with the bottom of the receptacle whereby air will be forced from the fan chamber into the drum 26 at the bottom thereof.

3. In a dish washingmachine, the combination of a receptacle, a foraminous drumtherein, an annular gear carried by said drumat the top thereof, means carried by the re- 26 ceptacle for supporting said gear and thereby suspending the drum in the receptacle, a shaft extending across the top of said drum, a gear carried by said shaft and in mesh with said annular gear and motor driven 30 means connected with said shaft for rotating it and thereby the drum.

4. In' a dish-washing machine, the combination of a casing, a foraminous drum therein, a ring gear carried by said drum,

means carried by the casing for supporting said ring gear, a shaftdocated along the top of said casing, a gear carried by said shaft and in mesh with said ring gear, motor driven means for rotating sa1d shaft, a fan 40 housing carried b said casing, a fan therein and also driven y said motor, and means communicating w1th said housing and extending along the bottom of the drum and having perforations for the passage of air into said drum.
